Just wondering how they work? Is it a random thing or is it something that needs to be requested? Ive read on here from many people getting great upgrades including value resorts upgraded to moderate and in some case deluxe resorts. During this process is there a charge or is it free based on availbilty? Im kinda clueless when it comes to this. Im going down in October staying at ASMo and looking to get the most for my money! Thanks any and all info is greatly appreciated!
